Background: We report a rare case in which closed reduction was successfully obtained for iatrogenically displaced fracture-dislocation of the humeral anatomical neck with a favorable clinical outcome.

Case Presentation: A 53-year old postman suffered from shoulder dislocation with an undisplaced fracture of the humeral anatomical neck which was initially undiagnosed. After the first attempt to reduce the dislocation of the shoulder joint by Stimson's method, complete displacement of the fractured humeral anatomical neck occurred. By closed reduction under general anesthesia, the displaced humeral head was successfully reduced and was subsequently treated by conservative therapy using sling immobilization. Follow-up by MRI two years later showed no evidence of avascular necrosis of the humeral head. The patient showed a satisfactory range of motion of the affected shoulder joint.In the present case, the blood supply was partially preserved because a part of the lesser tubercle remained attached to the displaced humeral head.

Conclusion: Based on this experience, we concluded that closed reduction might be attempted before deciding to perform an open reduction and internal fixation for displaced fracture-dislocation of the humeral anatomical neck.

Importance: Airway stenosis is a rare but debilitating disorder that significantly degrades the quality of life in affected patients. Treatments are primarily surgical, and disease management lacks established medical therapies. The North American Airway Collaborative held its third symposium at The Johns Hopkins Hospital in Baltimore, Maryland, on April 15, 2024, focused on strategies to advance the care of these patients.

Background: The neck, and specifically the prominence of the thyroid cartilage, can be considered a marker of male gender, which is often unwanted by transgender women. Chondrolaryngoplasty is traditionally performed using an open transcervical approach, which, while effective, leaves visible scars that can compromise patient satisfaction. Recent advancements, such as the transoral endoscopic vestibular approach (TOEVA), have emerged as promising alternatives, eliminating external scars and improving esthetic outcomes.

Importance: Cutaneous pyogenic granulomas (PGs) are commonly encountered, benign, vascular tumors, in which epidemiologic factors have been variably reported, in part, due to sample size limitations and a focus on either adult or pediatric patients.

Objective: To assemble a large dataset of pathologically diagnosed PGs across the continuum of age and investigate patterns of PGs by demographic factors, including age, sex, and anatomical location.

Design, Setting, And Participants: This retrospective case series included case reports of patients with pathologically confirmed PGs of cutaneous origin reported between April 1, 2010, to March 31, 2020.
